Ovulating twice in a cycle

Hey ladies, I was just wondering something, I have read different opinions on this subject, however I have my own. I think it is possible to ovulate twice. In fact I think that may be one of the reasons I am often a week late or so. I have the ovulation pain and stringy CM about a week apart. I think it could explain a lot of fraternal twins. Does anybody else think that they do?

The first half of a woman's cycle is dictated by Estrogen. temps are low to normal.

There is a significant dip in temps on the day of ovulation. Ovulation typically (not always) happens 14 days prior to a woman's next period.

The egg lives 12-24 at most. (Sperm lives up to 5 days in the fallopian tubes when under the right cervical fluid conditions).

Once ovulation is over (12-24 hours), whether pregnant or not, the body releases Prosterone to ensure a stable pregnancy. Prosterone is necessary to sustain a pregnancy, so the body produces it at this time (post ovulation - PMS) "just in case". Progesterone dictates the second half of a woman's cycle.

Progesterone heats up the body. The temps prior to ovulation will give a hint to post-ovulation temps. If her temp was 98.1 prior to ovulation (in the evening), it may be 99.1 during PMS.

A woman is unable to ovulate twice, but is however able to release more than one egg during her ovulation window.

A woman's temp drops signalling her period is about to arrive. If her temps stay high for 18 days in a row, its very possible that she is pregnant. Her temp will remain warm until delivery.
